This letter introduces radio frequency(RF) characterization of ink-jet printed coplanar waveguides (CPW) with and without strain. Kapton is selected as flexible substrate with different sintering temperature. With optimized inkjet printing parameters, well defined patterns with high resolution yield low attenuation constant even when operated up to 67GHz. Finally, we demonstrate that the RF performance of CPW is barely affected by bending.
